Simulation analysis on temperature field in induction launcher

The launcher is one kind of discharger that can push forward the armature with the electromagnetism. in launching the course, because the drive coil suffers the very big quantity of heat, the drive coil and armature is made to melting probably, and then affect the normal work of whole launcher. Produce and action course of temperature in the launcher is complex and calculated difficultly. So, the temperature in the launcher is analysis using finite element method. in this calculation, and the results are verified by experiment. So, basic principle of induction launcher is obtained.
